.TH SETCAT 3C "February 17, 2023"
.SH NAME
setcat \- define default catalog
.SH SYNOPSIS
.nf
#include <pfmt.h>

\fBchar *\fR\fBsetcat\fR(\fBconst char *\fR\fIcatalog\fR);
.fi

.SH DESCRIPTION
The \fBsetcat()\fR function defines the default message catalog to be used by
subsequent calls to \fBgettxt\fR(3C), \fBlfmt\fR(3C), or \fBpfmt\fR(3C) that do
not explicitly specify a message catalog.
.sp
.LP
The \fIcatalog\fR argument must be limited to 14 characters. These characters
must be selected from a set of all characters values, excluding \fB\e0\fR
(null) and the ASCII codes for \fB/\fR (slash) and \fB:\fR (colon).
.sp
.LP
The \fBsetcat()\fR function assumes that the catalog exists. No checking is
done on the argument.
.sp
.LP
A null pointer passed as an argument will result in the return of a pointer to
the current default message catalog name. A pointer to an empty string passed
as an argument will cancel the default catalog.
.sp
.LP
If no default catalog is specified, or if \fIcatalog\fR is an invalid catalog
name, subsequent calls to \fBgettxt\fR(3C), \fBlfmt\fR(3C), or \fBpfmt\fR(3C)
that do not explicitly specify a catalog name will use \fBMessage not
found!!\en\fR as default string.
.SH RETURN VALUES
Upon successful completion, \fBsetcat()\fR returns a pointer to the catalog
name.  Otherwise, it returns a null pointer.
.SH EXAMPLES
\fBExample 1 \fRExample of \fBsetcat()\fR function.
